摘要 |
The invention refers to a plate heat exchanger for treatment of a medium. The plate heat exchanger comprises a number of compression-moulded heat exchanger plates (1), which are piled beside each other in a plate package (2) and which form first plate interspaces (5) for the medium and second plate interspaces (6). The first plate interspaces and the second plate interspaces are provided in an alternating order in the plate package. The plate package (2) encloses an evaporation section, a separation section and a condensation section. The evaporation section is arranged to permit evaporation of at least a part of the medium flowing through the first plate interspaces. The separation section is arranged to separate non-evaporated liquid from the evaporated part of the medium. The condensation section is arranged to condense the evaporated part flowing through the first plate interspaces.
